If you know two things about the new movie “Crazy Rich Asians,” you probably know these: 1. It’s the first Hollywood studio film about an Asian-American character’s story in over 25 years and 2. It features luxurious fashion. And so it makes sense that the cast of the “Crazy Rich” movie would be dressed to impress at their Hollywood premiere. But several cast members took it a step further on the carpet for their landmark film: They wore ensembles by Asian designers as they posed for photos and gave interviews outside of the TCL Chinese Theatre.
